Let's say: if you want to assess the growth of productivity of a certain country during a period of time - use PPP GDP figures, BUT if you want to compare current productivity of say two countries against each other - use nominal GDP figures. Any opinions?
I think that measuring the growth in productivity of a country over time should be done in real GDP, not PPP GDP. If you're only looking at one country then you'd want to take the real GDP value as it mitigates inflation (thus, showing you only how much productivity increased rather than prices). Additionally, the currency of that country makes no difference because it's the same currency that's used year after year. I think PPP GDP should be used when comparing the productivity of two countries because of currency differences. For example, comparing a GDP value in British Pound versus US Dollar is meaningless because each currency is valued differently. This is when you'd want to use PPP to compare GDP.
I had an idea but some doubts. Your explanation solidified my understanding. Thanks a bunch for taking the time to make this video. I wish those who did not like "like" on the video would explain what they see wrong with this video.
Mmmmm TI-85 Rom... Would it be accurate to measure this against the population? In my mind it would be similar to an artificial interest gain in a bank account where that interest is actually lower than inflation in currency. Say you made $50 one year on an account with $20,000, but inflation for that year was 1.7%. Effectively, you've still lost money. The point would be that even if production goes up, it could and probably does go down per capita.
@NZSideways8 no, that's not because of black background. It's because the video compression tries to encode only the changes. In these screencasts of an image painting program, virtually nothing changes from frame to frame, making this extremely efficient. The codec mostly only has to update the area under the tablet pointer. The same would be true for images with solid white background or even photos in the background.
I dont know if many people notice, but the fact that most of these videos are black makes them really small, the 720p version of this is only 14MB - crazy. My point is that it makes them easy to stream on low bandwidth plans.
